Thank you all for your nice comments and advice!
Judge my happiness when I came home from office today and found a rather big parcel on the kitchen table, my pen had arrived

Oh what a lovely instrument
But, all good things has to come to an end... I ordered a International with medium nib, somehow the retailer has messed up and sent me a pen with a fine nib

This was the last Duofold in stock, if I want to return it for the correct one I will have to wait 4-6 weeks - someone just went from number one to number 100 on my list...
Now, what should I do? Do you think I'm alright with a fine nib? As told before, I will use the pen daily during client meetings ( not a consultant but a ... wait for it .... here's a cliché for you ... I'm a insurance broker ... and now a insurance broker with a fountain pen

)
What to do, what to do?
Kind regards,
Karl
EDIT: I've decided to keep the pen, despite the "nib mishap". I went through agonies in making the decision, but after reading some of the threads in the FAQ section I feel comfortable in my decision. What the ****, I guess I'll get another pen pretty soon anyway...
